Do All Cells Have Membrane?

Have you ever wondered if all cells have a membrane? The cell membrane is a crucial component of all living cells, serving as a protective barrier that separates the interior of the cell from the external environment. This semipermeable membrane plays a vital role in regulating the passage of substances in and out of the cell, allowing for essential processes such as nutrient uptake and waste removal to occur. But is the presence of a cell membrane a universal feature of all cells?

Cells are the basic building blocks of life, and they come in various shapes, sizes, and forms. While the majority of cells do indeed have a membrane, there are some exceptions to this rule. To understand why this is the case, it is important to delve deeper into the world of cell biology and explore the diversity of cell structures that exist in nature.
